I went through the agony of trying to print a 11MB PDF file on ancient P3/750 machine with 256MB of memory. The Adobe PDF Reader crashed and stopped printing after 2 pages (of appx 50) whatever I tried -- after a decent 70min wait..

Swapped to this and printing started immediately and didn't have any trouble. Extremely light-weight replacement for Adobe's own product and should be the only one ever to cinsider being installed on an old computer.
